TT Spit F. (engl)

TT Spit F.Although the Spit F. is based on the TT 18-Watt platform, it has not much in common with the kit of the Marshall 18 Watt.

The Spit F. is a full Matchless Spitfire clone with a straight forward design and all benefits which one would expect from a classic single channel tube amp. From clean to mean, purists will get a lot of sound for there money.

The Stand-By switch is not a mute switch. In Standby a small current flows, which helps to protect the switch and the rectifier tube but won't mute the amp totally. If one does not want this protection but a full muted amp than one can remove the resistor (R20) which is paralleled to the switch. We do not recommend this modification, use it on your own risk.

Warning !

Care is necessary during construction! Even though this is a low-watt amp, the voltages used are potentially fatal. This amp is NOT a beginner's project!
A successful build requires that you can read (and understand!) a schematic diagram, you know how to use various measuring devices, and you have some experience working with voltages over 60V.
